BULLETIN-BOARD.

SPECIFICATION forming* part 0f Letters Patent NO. 583,417, dated May 25, 1897.

i Application filed December 18, 1895. Serial No. 572,501. (No model.)

To a/ZZ whom t may concern.-

Be it known that I, MARTIN PETRY, a citizen of the United States, and a resident of the city of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Bulletin-Boards, of which the following is a speciiication.

This invention relates to improvements in bulletin-boards for use by newspapers, theaters, and the like.

The object of my invention is to provide a new and improved bulletin-board which is so constructed that the words and sentences for imparting the news or information to the public can be built up or put together within the building and rapidly applied on the bulletin-board or removed from` the same, the characters being adapted to be used over and over again, thus doing away with the neces-A sity of applying the characters individually to the board, which is a serious drawback, especially during inclement weather, consumes much time, and is connected with more or less danger, and is apt to cause mistakes and omissions.

The invention consists in the combination,

for securing the rods in place on the frame,

the rods extending across the glass front, and the characters on the rods appearing on the face of the glass front.

The invention also consists in the construction and combinat-ion of parts andde'tails, as willbe fully described hereinafter and finally pointed out in the claims.

In the accompanying drawings, forming a part of this specification and in which like letters of reference indicate like parts in all the views, Figure 1 is a front elevation of Iny improved bulletin-board. Fig. 2 is a vertical transverse sectional view of the saine. Fig. 3 is an enlarged perspective view of details, parts being in section and others broken away. Fig. 4 is an enlarged detail vertical transverse sectional view showing the. con- 5o struction of parts. Fig. 5 is afront elevation of a modified construction, parts bein gbrokcn away. Fig. 6 is a vertical transverse sectional view of the same, parts being also broken away.

A transparent or translucent pane A of glass of the desired size is held in a frame B of suitable size and the desired design. The glass pane may be provided on the face with transverse rectangular grooves C, suitably spaced,as shown in Figs. 1, 2, and 4, or the 6o face of the glass pane may be left smooth, as shown in Figs. 5 and G. The frame B may be suspended by brackets D from` a building or other support, and an electric light @placed behind the frame, or the frame may be constructed in the shape of a box E, which can be placed on any suitable support. In such case a series of electric lights F can be placed into a box behind the glass front. The characters G, such as -letters or numerals, are 7o made of some opaque material, such as metal, and are each provided on the back and at or near the center with a rectangularvloop H.

-A rod J is provided at 011e end with afork or eye K, and the opposite end is provided with a removable fork or eye L, said forks being attached to rectangular arms M at the ends of theprod and of such length that when said forks or eyes rest on the front of the frame A the rods J rest Ion the glass front or in the 8o grooves C in said glass front.

' The detachable arm M, carrying the fork or eye L, is preferably provided at its inner end with a screw-threaded apertureinto which a threaded stem J on the end of the rod J can be screwed. When said arm is detached, the characters can easily be slipped on the rod and properly arranged. Then the detachable arm is screwed on and the rod with its characters placed in front of the glass front, the 9o loops on the characters with the rod passing into a groove C or resting on the face of the glass front, as ,shown in Fig. 6. At each end of each groove C a threaded pin N projects from the front 'of the'frarne A, so that when 95 the rods J are placed on the front of the bulf letin-board the said threaded pins pass through the eyes or forks K and L. Then thun1b-screws O are screwed on said threaded pins N. The words or sentences can be put zoo ice they do not stick to the together on the several rods J within the building and can be carefully examined before the rods are applied. n,

The several rods bearing the words and sentences can easily be applied on the frame A or removed from the same, thus permitting of changing the bulletins very rapidly, as fresh bulletins can be built up inthe oliice before removing those on the board with a suieilent supply of rods .I and characters. This is of great importance, especially in displaying election-returns and the like.

The Words and sentences appear clearly and distinctly, the letters can be spaced correctl y, and the persons attending to the board need not be exposed to the inclemencies of the weather for any undue length of time.

In case the letters are covered With snow or glass front, and in case they freeze to the rods can easily be thawed off in the building, thus presenting great advantages over bulletin -boards in which the individual characters are singly applied on the glass front.

As the rods are preferably made of highlypolished brass, the light from behind the glass is so deflected that little or no shadow is cast bythe rods.

Ilaving thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. .In a bulletin-board, the combination with a frame, of a glass pane held in the same, rods extending across said pane, on the face "thereof, eyes on the ends of said rods, of which eyes, one on each rod is removable, pins proyjeeting from the front of the frame', on which pins the said eyes can be placed, meansfor locking the eyes in place on the pins, and characters provided on their backs with loops of such shape and size as to adapt passing a rod, such as aforesaid, through them and thus holding the characters on said rod in front ot;`

the pane, whenthe rod is locked in place in front of the pane, substantially as herein shown and described.

2. In a bulletin-boardJ the combination with a frame, of a glass pane, held in the same;L

means for locking the rods in place on the frame, substantially as herein shown and described.

3. In a bulletin-board, the combination with a frame, of a glass pane held inthe same, which frame has a series of transverse grooves in its front face, rods extending across said pane and fitting in the grooves, eyes on the ends ot' saidrods, of which eyes one on each rod is removable, pins projecting from the front of the frame, on which pins the said eyes can be placed; means for locking the eyes in place on the pins, and characters provided on their baclswith loops of such size and shape as to adapt passing a rod, such as aforesaid, through them and thus holding the characters on said rods in front of said pane when the rods are placed in the grooves in the pane, substantially as herein shown and described.`

In testimony that I claim the foregoing as my invention ,l have signed my name, in presence of two witnesses, this 9th day of Deceniber, 1895.
